Title:
DISPLAY DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2010/116569
Kind Code:
A1
Abstract:
Disclosed is a liquid crystal display device (1) which comprises a protective plate (11), a double-sided tape (13a) that serves as an adhesive layer, a polarizing plate (15b1) and a liquid crystal substrate part. The outer edge of the double-sided tape (13a) is positioned inside the outer edge of the polarizing plate (15b1). When affected by the temperatures, humidities or the like, the polarizing plate (15b1) shrinks in the h1 direction. The double-sided tape (13a), however, is not affected by the shrinkage of the polarizing plate (15b1) and thus no air bubbles are formed therein, since a burr portion (21) of the polarizing plate (15b1) is not covered by the double-sided tape (13a). Moreover, even when the polarizing plate (15b1) swells in the h2 direction, the double-sided tape (13a) is not affected by the swelling. In other words, the influence of shrinkage/swelling of the polarizing plate (15b1) on the double-sided tape (13a) can be reduced by configuring the double-sided tape (13a) to have such a small size that the burr portion (21) of the polarizing plate (15b1) is not covered thereby.
